Install Kali Linux Tools Using Katoolin3 In Ubuntu 20.04 LTS

This step by step guide explains what is Katoolin3 and how to install Kali Linux tools in Ubuntu, Debian and other DEB-based systems like Linux Mint and Pop_OS!.

Introduction to Katoolin3

As some of you might already know, Katoolin is a Python script to install Kali Linux tools in Ubuntu, Debian and other DEB-based systems.

If you're a security researcher or enthusiast, Katoolin allows you to install any Kali Linux tools of your choice on top of your Ubuntu system in couple minutes.

It seems that Katoolin is not being updated regularly (the last commit was April, 2019) and it doesn't work in recent Ubuntu versions. The Caveats started adding up due to lack of maintenance.

Fortunately, someone has taken up the torch and is keeping a very stable branch of katoolin. Say hello to Katoolin3, a fork of Katoolin, that helps you to get your favorite Kali Linux tools on Debian, Ubuntu and its derivatives like Linux Mint. Katoolin3 is completely free and open source program.

Important Warning: It looks like the Katoolin3 messes up the existing repositories. Many users have complained that Katoolin3 removes the GNOME DE, and other packages that are not even related to Katoolin when they try to uninstall Katoolin. So i strongly I suggest you to try it in a test machine for a while and see if it works perfectly.

Katoolin3 Features

Katoolin3 offers several improvements over katoolin as listed below.

• Katoolin3 is ported to Python 3. Katoolin is written in Python 2.x.
• It provides up-to-date packages. The old katoolin uses an outdated package list.
• The old katoolin breaks if a package isn't available in the repositories anymore. Katoolin3 detects the missing packages and simply ignores them.
• Unlike old Katoolin, it is possible to remove all packages installed by Katoolin3. You can remove packages individually or all at once.
• Some user have complained that they can’t update or upgrade their Ubuntu OS after installed old Katoolin. This issue has been addressed and fixed in the newer Katoolin3 version. The upgrade won't break your system, because the Kali repositories only get enabled during the runtime of katoolin3.
• The old katoolin modifies and even deletes important system configuration files. These potentially dangerous operations have been changed in Katoolin3.
• It is difficult to add new packages to package list in the old Katoolin. Not anymore! Maintaining the package list just got better and a lot easier with Katoolin3.

Install Katoolin3 in Ubuntu 20.04 LTS

I have tested Katoolin3 in Ubuntu 20.04 LTS server edition. However, It should work on other Ubuntu versions and derivatives.

Katoolin3 requires the following prerequisites in your Ubuntu system.

• Python >= 3.5.
• Git.
• sh, bash.
• python3-apt.

These packages comes preinstalled in latest Ubuntu 20.04 LTS, so you probably don't need to install anything.

Also, make sure you have enabled [universe] repository.

$ sudo add-apt-repository universe

Clone the Katollin3 GitHub repository using command:

$ git clone https://github.com/s-h-3-l-l/katoolin3

Please make sure the repository name is correct. In the above URL, it should be two lower case “L” letters in the word "s-h-3-l-l".

The command will clone the contents of Katooolin3 repository in a local folder named "katoolin3" in the current directory.

Go to the katoolin3 directory:

$ cd katoolin3/

Make the install.sh executable:

$ chmod +x ./install.sh

Then install Katoolin3 using command:

$ sudo ./install.sh

Upon successful installation, you will see the following message:

Executing: /tmp/apt-key-gpghome.r4OwC90o2Q/gpg.1.sh -qq --keyserver pool.sks-keyservers.net --recv-keys ED444FF07D8D0BF6
Successfully installed.
Run it with 'sudo katoolin3'.

Please note: If you get the error "Please install the python3-apt package", please make sure katoolin3 runs with exactly the same python3 version as the python3-apt package. On modern distributions python3-apt is only for python3.7 and on older distributions python3-apt is only for python3.5. Katoolin3 has to be run accordingly with python3.7 or python3.5. In Ubuntu 20.04 LTS version, I don't have any issues with Katoolin3 installation.

Install Kali Linux Tools Using Katoolin3 In Ubuntu 20.04 LTS

To run Katoolin3, enter the following command:

$ sudo katoolin3

Katoolin3 will add necessary Kali Linux repositories on your Ubuntu machine and update the sources lists.

Once the repositories are added and the source lists are updated, you will see the Katoolin3 main menu.

Important note: Please note that you should not update your packages, upgrade your system or modify your package cache in any other way while katoolin3 is still running. Always close Katoolin3 before updating system or modifying package cache. Unlike the old Katoolin, the new Katoolin3 will not break the system while upgrading because the Kali repositories only get enabled during the runtime of katoolin3.

As you can see in the above screenshot, the Katoolin3 main menu has 9 sub-menus and each sub-menu performs different operations.  To open a sub-menu, just enter the corresponding number.
